The lowest monthly commission that a salesman earned was only 1/5 more than 1/4 as high as the highest commission he earned. the highest and lowest commissions when added together equal $819. what was the lowest commission?

Commission that a salesman earned = 1/5 more than ¼ as high as the highest commission earned

Highest and lowest commission = $819

What was the lowest commission? Let x be the highest commission

Solution will be:

1.2 (1/4x) + x = $819

1.3x = $819

x = $630

819 - 630 = $189 is the lowest commission
